Security Risks of opening ports on cPanel server
| Posted by kshazad86, 08-25-2012, 01:45 PM |
| I have a user who needs to use Port 1129 to use a credit card payment gateway (LinkPoint API). How can I open up the port whilst making sure that only this application is able to use this port?
Note: I am running a cPanel/WHM server with ConfigServer Firewall.

| There is no good way to make sure *only* that application uses the port that I know of. You could perhaps limit traffic on that port to that certain user but that's a pretty advanced firewall rule (if I'm even remembering correctly).
I'd simply check the payment gateway's documentation to make sure it uses that port, and then open the *outbound* port only, that is, if you make changes such as these on your platform for customers.

| Thanks, so this rule would be fine?:
tcp|out|d=1129
Does anyone know what IP address linkpoint API uses as I think I can create a firewall rule that will only allow a particular IP address to access port 1129?

| netstat -an|grep 1129
and see where it's connecting to.

| I am not sure which IP address they are using to run their API. You can contact their support to get exact details. It is good idea to restrict certain IP address only for outbound port.
